Motor vehicle lighting device with a coupling lens and a transport and conversion lens

Abstract

A motor vehicle lighting equipment with a light source and an optical fiber arrangement, having an input coupler and a transport and transformation lens system. The input coupler has a curved light beam forming surfaces, which reduces the angle of beam of the light in these second sectional planes when penetrating the surface. The transport and transformation lens system has transformation lenses which have a mutual focal point. The light source is located in the mutual focal point. The light source is arranged in such a way on the side of the optical fiber arrangement located opposite of the light-emitting surface that all areas of the optical fiber arrangement conducting light from the light source are located between the light source and the light-emitting surface, and the one planar deflection area is arranged between the curved surfaces of the input coupler and the transformation lenses.
